This is a great deal. I am running this same RAM in my system right now. I ordered my 128mb budget stick a few months ago for the incredibly low price of $144, over $150 shipped. Now I can have another 128mb of excellent RAM for almost half of what I paid for it before. I am currently running my stick at 143fsb 3-3-3 7t,9t on my CUSL2, but I have taken it over 150fsb at these settings. I have been able to run it at 2-2-2 5t,7t on 143fsb, but it wasn't that stable. I would get random "explorer" errors in Win98se. It seemed to work great at 2-2-2 5t,7t at 133fsb, but I didn't do extensive testing, so no guarantees on similar results.
